That definitely used to be true, and is true for almost all the members of this community, but I’m not sure it’s going to be true going forward, or even if it is actually true today. q
There’s no question that the V3 app (the newest one as of this writing) Has two separate parents in its DNA: the hub-based smartthings system and the previous “Samsung connect“ app which was used for Samsung smart appliances. Plus they folded in a better integration with Samsung smart televisions for model year 2018 and beyond.
All of that means that the V3 app Was clearly designed from the beginning to support some customers, quite probably a large percentage, who don’t have a hub. They have a television, they might have the refrigerator or the washer, and then they have some smart lights and a smart doorbell.
So I think we are going to be seeing more and more community members who don’t have a hub and don’t feel that they need one.
My concern from the design standpoint is that they appear to have defined all of the devices that can be discovered with superLAN connect as requiring a hub, even though those devices technically shouldn’t need one. I have one location without a hub myself, but have not been able to add several Wi-Fi devices that I thought I should be able to. But I haven’t seen confirmation of this hypothesis one way or the other.
Regardless of why some devices which don’t communicate directly to the hub are still listed as requiring a hub in the V3 app, The fact remains that they are. It’s quite confusing.
